Semantic Communications With AI Tasks

no code implementations29 Sep 2021 Yang Yang, Caili Guo, Fangfang Liu, Chuanhong Liu, Lunan Sun, Qizheng Sun, Jiujiu Chen

A radical paradigm shift of wireless networks from ``connected things'' to ``connected intelligence'' undergoes, which coincides with the Shanno and Weaver's envisions: Communications will transform from the technical level to the semantic level.

Alternating Fixpoint Operator for Hybrid MKNF Knowledge Bases as an Approximator of AFT

no code implementations24 May 2021 Fangfang Liu, Jia-Huai You

In this paper, we show one more application of this kind: the alternating fixpoint operator by Knorr et al. for the study of the well-founded semantics for hybrid MKNF knowledge bases is in fact an approximator of AFT in disguise, which, thanks to the power of abstraction of AFT, characterizes not only the well-founded semantics but also two-valued as well as three-valued semantics for hybrid MKNF knowledge bases.

Well-Founded Operators for Normal Hybrid MKNF Knowledge Bases

no code implementations6 Jul 2017 Jianmin Ji, Fangfang Liu, Jia-Huai You

In this paper, we address this problem by formulating the notion of unfounded sets for nondisjunctive hybrid MKNF knowledge bases, based on which we propose and study two new well-founded operators.
